Questions

Is there a KiCad symbol and footprint for the ADA4940-1ACPZ-R2?

Yes. The symbol is Amplifier_Difference:ADA4940-1xCP and the footprint Package_CSP:LFCSP-16-1EP_3x3mm_P0.5mm_EP1.3x1.3mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ADA4940-1ACPZ-R2?

LFCSP-16(3x3), with 17 pins. Its footprint is drawn on this page.

Where is the ADA4940-1ACPZ-R2 datasheet?

Analog Devices publishes it: the Datasheet link on this page opens it.

Where can I order the ADA4940-1ACPZ-R2?

JLCPCB lists it as part C654337, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ADA4940-1ACPZ-R2?

Parts like it in the library: the ADA4938-1ACPZ-R7 by Analog Devices, the ADA4940-1ACPZ-R7 by Analog Devices, the ADA4940-1ACPZ-RL by Analog Devices and the ADA4938-1ACPZ-R2 by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
